Colonel CE Day III wrote to the three Health Physicist Army Captains about depleted uranium before the Gulf War. Page 2 of this letter mentions Army Reserve First Lieutenant Douglas Rokke and asks the three Captains to share all of their information about depleted uranium with Rokke. Presumably, Rokke know nothing about DU before he was contacted by one of the other more knowledgeable Captains. As a First Lieutenant, Rokke was the junior officer of this group of four young officers.
